Worked Great For My Pups Issues!

By Kate

First, kudos to Chewy for the incredible service they provide!! I've ordered things that were delivered the next day!!
This particular item was necessary to help my dog get through a bout of tummy troubles, and along with a regimen that included other meds, he is 100% better and thriving on this food! He loves the flavor and most importantly, his tummy and stools are back to normal and he's happy and healthy again.
His vet recommended a month's supply of this food and then slowly transition him back to his regular food, but if his tender tummy requires him to be on this the rest of his days, then so be it- he's worth it!!
Thanks Royal Canin and Chewy!!

Baxter's godsend

By Salambeth

After trying 3 other different brands of food for my boy Baxter he always ended up with diarrhea. We went to the vet multiple times and with multiple treatments of probiotics. The probiotic would only work for a few days and the diarrhea would return. After trying different off the shelf foods the vet finally prescribed the GI Low Fat formula from Royal Canin. And finally after switching to this food the diarrhea finally cleared up for good. This was about 2 years ago and all has been well since.

This Food Saved My Dog's Life

By Casper

So, my 5-month-old Maltese Casper was diagnosed with Megacolon. His colon being too big for the rest of his body, it became VERY difficult and painful for him to poop! Can even say how many emergency trips for enemas! Anyway, we were afraid we'd have to put him down. But what felt like the last straw was THIS food...and I believe it literally saved his life. Casper is now 10 YEARS and doing fine.

Dog Owner of Dog w Sensitive Tummy

Have tried every expensive dog food to help my dog’s tummy. All but Royal Canin has left her gassy, indigestion and often vomiting. All other brands have worsened her pancreatis.. through internet research I read about Royal Canin and figured Id give it a try since everything else has failed. This stuff is golden for dogs with tummy problems. It has helped my dog regain her health back. She never has gas or indigestion anymore. No more vomiting either.

Finally, after almost a month of no interest in food!

By Izzy

Izzy is loving her new Royal Canine GI dry dog food. Her GI issues have calmed down to normal and she is anxiously awaiting her mealtimes again. This after almost a month of turning her nose up at any kind of food, we finally found the answer. Chewy supported us through this time and gave me an opportunity to help out an elderly lady with her senior dog who was also suffering from GI problems. Giving her the food that Izzy refused to eat probably allowed her dog to eat during the holiday season, and the elderly citizen a chance to heal after her surgery! We all benefited through the holidays, thanks to the excellent Customer Service policies of Chewy.com!

Sick puppy

After trying cottage cheese and rice for about 3 weeks with no success, our vet recommended adding this brand can food for the nutrients. She began to do much better. I wanted to try the dry as that’s best for her teeth so we did and she continued to do very well. We stopped the cottage cheese and rice and fed her just the dry. She loved it and is continuing to do well. It is much less expensive from Chewy and very convenient! Once they received our prescription, we received it the very next day! I recommend both the food and Chewy!

Love Love Love!

I had to go through 3 diet changes before I found this diet and my fur baby has been on it now for 2.5 years.
He used to get crazy hives on his back and diarrhea on and off as a pup and let me tell you it was not fun. Our veterinarian easily prescribed it and has been on it since.
This diet is great and Buster seems to love every bit of kibble.
Its also a bonus that Chewy.com makes it so easy to order!

Love it so far!

By Chelsea

My 3 year old dog has pancreatitis and it's been a long battle and the vet is thinking it may be something he struggles with for the rest of his life. I've been trying different foods (mostly science diet perscription), but when I went for a second opinion from another vet, I was recommended this food! My sweet boy now has so much more energy and actually gets excited again! Where as when he was on the science diet perscription, he was still groggy and didn't want to play with other dogs. I'm so happy with this food and I hope it continues to be a great one for him!!

On-time lifesaver

By Erika

My pup (Skittles) is a small girl and has terrible tummy issues. After many rounds of medication and a diet of chicken and rice, the vet recommended this Royal Canin Vet Diet. I ordered it that night. When it arrived, I took 3-4 days to switch Skittles over to this food and now she's doing great! She loves it, eats it without problem, and has not had any more tummy issues since then! (Note: I did consult with the vet on how much to feed her and I had to increase her portions due to the lower caloric value of this food over what she ate before)
